Two former rivals are thrown back together over the course of one steamy summer in the Hamptons, in this emotionally rich and devastatingly sexy debut rom-com for fans of Emily Henry, Carley Fortune, and Ali Hazelwood.

Sometimes one summer can change everything.

Charlotte Parker is in a rut. Recently out of a long-term relationship, stalled out at her nonprofit job, and desperate for a change, she jumps at the chance to spend the weekend at a coworker's friend's Hamptons cottage. Yet what Charlotte doesn't expect is that the "cottage" in question is more like a mansion, and the owner is none other than Jacob Morgan-Charlotte's high school nemesis.

And Jacob is exactly as maddening as she remembers.

But as one weekend turns into a summer, Charlotte realizes that Jacob is not nearly the same arrogant rich kid he was a decade ago. And as the thin line between loathing and lust begins to blur, Charlotte wonders if a summer fling with her once-sworn enemy could be just what she needs to shake things up. If Jacob Morgan, of all people, is capable of change, could the same thing be true for her?
